UNITED STATES PATENT OFFICE.

JULIUS ROEVER, OF NEW YORK, N. 'Y'.

MULTIPLE PHONOGRAPH.

Be it known that I, JULiUs Ronvnn, of the city of New York, county of Queens, and Sta-te of New York, have invented a new and useful Improvement in Multiple Phonographs, of which the following. yis a full, clear,'and exact description.

'My invention relates to improvements in multiple phonographs in which a wheel is used, the said wheel carrying on its circumference a series of records which are brought in turn or as d esiredI beneath there roducingy mechanism. Machines of this kind are used in public places and are operated after dropping in a coin, and it is necessary and and give a new list of pieces-or tunes.

The object of the present invention is to provide a device for supporting the records so that they may lbe easily and quickly changed, and so that when changed the mav chine may be assembled for operation again without any chance of jamming of the different parts so that there will be too much friction for the proper running of thelmechansm. To this end I provide a rotatable record wheel carrying record holders near its periphery, the record holders being supported by the wheel only at one end of the holder and at right angles to thesurface of the wheel. merely slipping them off and on the holder.

.In connection with the record wheel I provide a disk rotatable. with'the wheel and having cards or other means secured thereto indicating the name of the tune or piece of the corresponding record on the wheel, and an indicator1 set at a point where it is necessary to stop'in order to have a desired record brought under the stylus of thel reters indicate corresponding parts in all the4 views.

Figure 1. is a broken front elevation of a machine showing my improvements, and Fig. 2 is a cross sectional view through the center and the upper part of the same.

I have showny the invention in connection with the post or support 10 which supports the horizontal shaft 11, vsaid shaft'being held stationary in the post by the'lug 12. The record wheel' 13 is mounted upon the sleeve 14 `which is lcarried by the shaft 11 and ro- The records are changed byy tated thereon. vBetween the sleeve 14 and the shaft 11 I provide a bearing sleeve 15 and a set screw 16 so that the bearing will revolve withv the sleeve 14. The record wheel 13 is a metal disk or frame,` and is rigidly secured to the sleeve' 14 and-revolves with it. Along the periphery of the wheel are arranged the record holders .17 which are supported on the horizontal shaft 18.-

The shaft 18 is supported in the sleeve19,

the latter beingv rigidly secured to the wheel 13l and carries the ball 'bearings 20 and 20'I which allows for shaft 18.

At 21 on thelinner end of the shaft V18 I have shown a .pinion or friction disk securedv to said shaft, which can be operated by any desired mechanism for rotatingv the shaft and the record lholder on it. The record holder' proper 17 is mounted on the outer easy rotation of the 70'.

end of the shaft 18 and is held rigidly against the shaft by a set screw-22. It will thus be seen that-.I provide a means for mounting the record holder on the record Wheel so that the outer end of the holder is free, thus making it possible to change the records byV merely slipping them olf and. on over vthe end of the holder.

At 22El I have shown a brush loosely hung onv the sleeve 14 and having a weighted `end 22". This brush doesl nbt revolve with the sleeve 14 and Yrecord wheel 13,'but remains in an upright position. by reason of the weighted end 22", andtherefore as it is arranged to contact with a' record, it will keep.,

the record clean from dust and other'particles of dirt while the record is being refvolved under the reproducer.

In order that thenamelof the tune or song upon the .record'may` be indicated to one desiring to use the machine, I provide a disk 23l which is carried on a sleeve 24 and will rotate -n the shaft 11 at the same time with the record wheel 13, as the sleeve 24 is locked with thev sleeve 14 by the pin 25'. Openings 26 are provided near the outer Aedge lof the disk 23, and a spring 27 which is secured at oneend `28 to the inner ,surface of the disk 23, vand thus a card bearingthe name of the tune upon the phonographic record directly behindit may be supported plainly in vleW. i In order-to provide for centering the record'which'it is desired to hear beneath the reproducr, I provide "an indicator 29 which is rigidly supported on the shaft 11 and los l points 'Where' the record Wheel lshouldfstop,

Y in order that the desired record may be acted' upon by the mechanism of the reproducer. I have not shown the reproducer in the ldrawiings, as it forms no part of my present invention, but it would preferably be placed just above the record Wheel 13. The indicator 29 is attached to the thimbl'e 30 which tits over the outer end of the shaft 11, and is held rigidly in place by the spring pressed pin 31. This pin has a head 32 and ismov# ably supported in the casing 33 Which forms the lower .part o'l3 the thimble 30, by the spring 35' which abuts against the collar 34 on the pin and against the nut 36 which is screwed over the end of the casing 33. The spring 35 acting on the collar 34 presses the pin into 'the depression in the shaft 11, and thus locks the thimble 30 and the indicator .29 firmly in place. The inner edge of the thixnble 30 is provided with a collar 36 which abuts ,against the spring 37. The' spring 37 is secured to the outersurace of the disk (see Fig. 1b) and thus holds the sleeve 24 snugly against the sleeve 14, locking them irmly by meansot1 the pin 25. The operator, then, in order to change the records, simply pulls down the spring pressed pin 31 and pulls oi the thimbleeSO. The sleeve Q-fl carrying the disk 23 can then be pulled oit ,and the records changed by simply slipping them off anden the record l holders 17. As'the record holders are supported on the record Wheel 13 only at one end of the holder, it is evident that I provide a very simple and easy means for changing the records. lVhen the records have been changed, the disk is replaced and locked against the sleeve 14, and the indicator and thimble put on and secured to the end ofthe shaft, and the cards on the disk Q3 changed to correspond to the records. It will be seen that even though the man changing the records Were careless or incompetent, there'is no chance of putting the parts together so that they will be jammed and the mechanism not Work perfectly.

I claim:--

1. In a multiple phonograph, the combination of the shaft, a sleeve rotatable thereon, a disk secured to the sleeve, record holders supported on the disk near its periphery and atright angles tothe'fsurface thereof, a second sleeve onthe shaftabutting With the first sleeve, a vdisk'supported on the rsecond sleeve locking means on .the sleeves so that they will rotate in unison, and a thimble removably secured to the Vend of'the shaft and abutting with thesecond sleeve.

2. In a multiple phonograph, the combimounted on vthe shaft and rotatable thereon, a record Wheel rigidly supported on the sleeve., a second sleeve mounted on the shaft and locking with the iirst .sleeve and rotatable therewith, a disk mounted on the sec- (so nation with the horizontal shaft, a sleeve ond sleeve, a thimble fitting over the end of y the shaft and abutting with the disk7 means in the thimble to lock it on the shaft, and an indicator rigidly secured to the thiinble.
